I had a problem with this the other day... My bill was up to $171.00 and it was only the 12th! Turns out the meeter guy couldnt get a reading and he came to the door but i didnt answer... and I was fucking with him.. cuz he started to walk in my back yard and I yelled HEY! then hid... just to see what he'd do.. and I didnt know he was with the "tricity" company.. so he decided to give me a huge reading... turns out the bill was only 78 bucks... but will still go up since it was only the 12th..
Im running 400w HPS 80w tubes... and 130w CFL plus a computer on ALL day and a tv on almost ALL day...
I honestly dont think your electricity company gives a shit whether your bill is 500$ just means more money for them...
However I do think it looks odd when you have an average of 50$ a bill.... and now its over 100.... At my house we have NEVER had a bill over 100 $ and this month I will for sure beat that record.... only time will tell on what it will be though...
But I still dont think its enough to have a cop at your door all of a sudden...
